` VBe it known that I,'- EowiN Cournino SHAW, a citizen of the UnitedStates, and a. residentoff the city-` of Akron, in the county of Summit and State of'hio, have Vinvented certain ynew and useful Improvements vVehicle-Theel Rims, of whicl 1 the following is a"specificatiom'refereiice being had to thedrawings forming: a part thereof.

10 My invention relates to that' class ofi/ehicle wheel .rims adaptedfor vwith tires of resilient materialf'. Q

' t articularly relates tio rims upon `which :i resilient tire caribe detachably mounted,

i A and' to rimswhicli can beapplied to -and de-r tached from the wheel felly at will.

It has for vits yespecialobjects theprovii sion of means in thesameA wheel rim Whereby notonly can the tir'ebe quickly and easily '2Q attached thereto orfdetached therefrom,but

'f alsqthc rim itselfcan be readily attached to and quicklyV detached from a Wheel fellfy. j

` Wheel rims have heretofore been devised intended to facilitate 'the detachable at- 25 tachment of tires thereto i;` other rims have been devised 'intended to he `detachahlyv atlixed to the `wheel fellyiwith my improved construction I haje attained the combination of both of these desired ends in a` single Myrimisya medium of rapid and ready 'attachment and detachment com mon alike to tire and felly, and is ca able of attaining these ya'idivantages with eac Il attain vthese objects primarily by employe ing' ay split ,ring and endless tire-retaining ila'nges 'or' rings mounted thereon, and by the'cbnstruction and-means hereinafter scribedywhereby the rit'n is capable of contracti'ng to receive the tire and expansion to 40 retain it. and the self-contained structure resulting is itself capable of quick and positive attachment to-t e wheel felly by. Wedgin vengagement therewith..

Iy improvedy rim is n'ot restricted in its' field of uaeuiness to any particularclass of tires, nor to. any particular type of fellies,v as will be aparentg to 'those' sill art; It haseen vhere illustrated as a plied to pneumatic tires but it will be read' y understood that without departing from thespirit. of this disclosure it may be adapted to solid or cushion tires with iegual advanj of a pneumatic tire of the clencher typeA tage. In the classof pneumatic tires', the clenclier type has been.v chosen for illustra-V tion; but my improvement` can be applied,

vas is clinicas, toflany other type ofthe cias i' fabric; the simplification of inea-ns of at-l taehmentgl-bothof the "tirato the rim and- A the riinto the felly;a posi't1\"e engagement edV in theas for exani'plmto tl'ieDunl'op tire, KK v plemodiications of the means shown.

Among rthe adifanta'es attainable Wit-h .i v my mi `rov'edf rim 1sA that of a self-contained cq 't1re.,n iereb an injured .tire or rim n'iay be rapidly rep aced ywith* a sound "tire,V or' a .v deflated tire by an inflated one. As an ill'usy trationof itsy advantage, it may be noted i lthat in automobile practice'it is customary 65 to' carry a'spa-re tire to replace one that may' f becomev unserviceable. i Under present nietli- A Y rods, in case the tire to be replaced is a pneui matic one, the ltiremiist removed from t therini; another set inits` stead'and there- 79 after,V infiatedi By my vinvention the spare tire-may be transported already :inflated andl mounted VuponV its rim, as` selfscontained structure ready for instant setting, in lieu lof, the damaged tire and its'rim. The rims 75 construction facilitates the slib'st'iti'itionof -y another tire upon it; and its inflation, ini 1 tra'nsitl The delay incident to inflation of a s tire afterfsetting is o byiated by the substij` tution of a 'tire that lisfi'eady to run. s SQ'V timeV is oftenV 3 1!! elenieiitof material `value, y f

asinraeesg` the. use of my self-containedtire thus avoids a serious' handicap. Other feap tures of advantage are theeasel and convenf -ience' of-.handling when the tire has to be 85,. ,rcinoyed Vfrom therim, 'enabling this to be done'rapidly andV without any special tools .or `appliancegor extra parts; asavin of the wearupon the tire lcase which isl inci enty to theuse vof tire tools upon inex-tensible 9 0" of leach to the other, and apositiye dischavoidance of condi-tions liablefto Vinjure they i inner tube,` when ychanges are made, as hy the collection of kdirt: moisture inthe tirek case when the change is.y made slowly or.

under ditlicult conditionsof road work.'

f Other features of adyafntage' inherent; in l the construction of my improved 1 rim are illustrated in ,the accom anying ldrawings in which isvshown one o several means ofpracticing my invention as applied to pneu- ,105 matic tires ofthe clencherty In the drawings Figure 1 s ows s; section upon .reinavable split rim montedupon-a fixedl thewlicel fell'y. Fig. 2 shows 11* Aif: swims split rim in its normal position, and also showing the. means 'for Vattaching the split rim-to the fixed rim and the fixed rim tothe felly.. Fig. 3is a longitudinal sectionalview of the split rim bridge piece and fixed rim.

. Y. .Fig 4 is a transverse sectional `view on the line X-X ofrFig. 1. Fig. 5 is a transverse f sectional view on the line Z--Z of'Fig 1, the

fixed rim, felly, and valve capbeing omitted. Fig. 6 is a view in elevation showing the splitl rim contracted byfoverlapping its ends showing the detachable split rim expanded,

to permit the annulart'ire flanges and-tire to be mounted thereon. Fig. 7 is a like view to its normal position and locked therein.

These drawings., illustrate specific forms of annulartire retaining flanges, detachable Y and fixed rim, and means-fonpromoting they xvedgi-ng engagement between the removable and the fixed rim.y yThese yseveral'elements and their accessoriesmay be variously modified so long as their several respective func- 'tions are erformed relativelyto each other, vwithout a tering the respective combination of elements; for example.,the removable rim t and the fixed rim may be of a number of` forms in cross sectionkv so long as they are so censtructed that they are adapted to coo erate in mutual Wedging engagement. Trl'le removable rim itself ma beadapted in many ways to retain the en ess tire retaining flanges mounted upon it, Ydepending upon the forms of these flangesin section, which in turn will. be varied to correspond to the tire to be retained. They essential feature of the deta'ehable rim is that it shall be a split rim, and of the tire retaining flanges that they shallrbe endless. Similarly the meansot permitting the wedgin engagement between the detach-able rim an the fixed rim may be varied,` and in like manner'the means for maintaining the split rim in its normal position admits of many modifications. Y

Throughout the several figures like reference numerals are used to indicate the same parts. v

The detail of the several views is as fol' lows: 1 is a wheel felly; 2 is a fixed rim.

mounted thereon; 3 is a detachable rim transversely splitl at 4 to permit its expansion and contraction; 5 arev endless tire retaining flanges mounted upon rim 3 and held against laterally' outward movement by the flan es 6, 6 formed integrally upon the remove le rim 3.4 The detachable rim 3 has 'formed' integrally Vwith itdownwardly extending annular flanges 7 and 8 adapted 'tofengagefwith upwardly projecting annular' flanges 91 and 10 formed upon the fixed rim 2 as shown inv Fig. 4. Formed upon the detachable rim 3 1s the inwardly proiectmg fixed rim. f

lug 11 .adapted to seat inthe slot 12 in thel n The detachable rim also' carries f a bridge piece 13, one end of which isriveted thereto by the rivets V14, 1'4 andthe other endy of which. rojects beyond the splity l in .t-he rim 3 an has formed'in its extrcm1t a .slotted recess adapted .to receive the bo t 15, the fixed -ri-mhav-mg a'slot there-l through to' permit `the entry of the bolts. head therein. The fixed rim is attached to the fellyby any suitable means. Disposed 1 atsuitable intervals it has downwardly extending ears 16 overlyi-n the outer side of the feily,ywhic h are dr3 edto receive bolts-A i i 17 passing therethrough and` through the felly. These bolts are screw-threaded to receive the nuts 18. In the construction here *j I illustrated'the flan e 7 has a downward and outward inclined ace corresponding to the incline of the flange `9, which is a downhvr wardly beveled'taper,While the flange 8 hasv van inwardly anddowmnardly inclined face adapted tol correspond to the upwardlyr and e outwardly inclined bevel of the flange 10,7' which is itself slightly inclined.

The method of operation ofmy improved rim is as follows: Thesplit detachable rim 3is contracted asshown in Fig; 6 so that' its ends overlap.' Its diameter being thus contracted, the inner tire retainingflange 5 is passed overit and positioned against 'the inner rim G. The tire may be then passed stem 18 lbeing first passed through a hole provided therefor `in the detachable rim, and the outer tire flange 5 positioned thereupon' within and against the outer rim flan e 6. The rim 3 is then allowed to exan and the bolt at 15 is turned up locking' the bridge piece y13 under its head thus retaining.the extended rim in its normal poi sition s'shown in Fig. 3. The tire is then.`

inflated and by its inflation locks itself .against the annular" tire retaining flanges l 5, 'uponthe detachable rim 3. The tlre and rim thus present a self-contained structure adapt-ed to becarried as such ready forv rim an fellly provi 'ed therefor and the' lu 11 seated in its correspondingslot 12 an the head of bolt 15 'inv its .corresponding slot readily over the contracted rim, the valve l `of this struci is first (passed throu h the'v hole in the fixed Y in the fixed rim. The detachable rin'i is then l s able rim upon thefixed rim, t e slot 'in the brid ieee 13 permitting it to slidev beneat the head oflboltlf as the detachable rim is expanded I against the annular tire if i971;

Aretaining flanges 5 until they limit the motion; of the detachable rim. To remove the! detachable rim the operationis reversed; the nuts 18 beingremoved, the detachable krim at therside' opposite the valve steinisfirst slid 'off the fixed rim whenthe rimv and tire mounted thereon may be lifted from the l fixed rim. To remove .the tire from the rim i is the bolt l5v is withdrawn and' the rim con-V tiactedV as shown in F i0.' 6 when the Vouter annular tire retaining flange may/be lifted olf andthe tire removed from the detach# able rim, the side opposite the valve stein being first freed, when the tire may4 be .lifted upwardly, the yvalve'stem 'passing through` the slot in the'rinl. y v
